440 ftlbs is conservative? I think we'd like to hear about your forged internals now.

That's still a lot of torque. It's going to be a blast to drive though. Enjoy it.

That's where my concern is. When they fail it's catastrophic. Although I don't DD the car so I'm not SOL if it does

Catastrophic? It'll sound like a bucket of marbles got dumped under the hood. Then you'll hear the "marbles" bouncing off the bottom of the car. I remember it like it was yesterday. Save your heads and get that closed deck in there as soon as possible.

Yeah it ain't worth the scrap metal potential. Were it mine I'd lighten the tune or quit driving it until I could make it stout enough to use the power. having all that and needing to tiptoe around it defeats the purpose.

Well for one I don't Need to tip toe with the power. Yes it's not as safe as the stage 2 tune. Yes it's only a matter of time before I have a failure. You also have to understand we all do these mods knowing the potential hazards. (Pay to play) I've increased my odds of one of those hazards happening ten fold but their still is no guarantee the motor will last just as with a stock tune. I've babied the car since I bought it and still will continue to baby it as it's too new to destroy. But worse case scenario I've already accepted I may have to replace the long block and anything else that's damaged when she goes. I will be installing a stage 2 closed deck within 3 months. probably 2500 miles on the car if in that time. I appreciate the concern though guys it's a very stressful feeling.

My reasoning is 350 lb-ft is the accepted threshold for rod failure. Why tempt fate?

I'll log the finished map today for y'all and post it here. both 93 and e85. undyjr your build looks like a beast. I'll probably go that route or move to an ets kit with vband

I'm already back on 93 with a half a tank so I'll have to run it out before I can do the blend.

I guess I just enjoy living on the edge lol. disaster will strike I know. the only question I have is if it will happen before the rebuild or not. But you really are tempting fate with any motor when modifying it past it's stock power levels. Some more dangerous than others but out of all the blown FA20 motors most have blown on stage 1 or stage 2 tuned around 300whp/300wtq. Time will only tell though. When I get off work I'll go do some logs and let y'all look through them and pick them apart. I'm always up for criticism and personal opinions. So feel free to pick the logs apart hard. I have a log from right before final tune I'll post now.

I don't think anyone is saying that you need less power. Probably just less boost at lower RPM where you shouldn't be WOT anyways. Just ask your tuner to make it a flatter boost curve.

This is something I asked of him while tuning the car just cause if i take it in for tires rotation and balance i dont want a mechanic to WOT below 3500rpm not knowing what can happen. Lets be real they all drive it like they stole it for test drives. I think it just slipped his mind as we are going through it again via e-tuning as well as we have to fix my cold start. I still haven't driven the car since taking it off the dyno but once I do I'll get some logs and let everyone take a look at them.
